The River des Peres Clean Stream Clean Up event brings the community together to restore and protect a vital local waterway. In partnership with Olivette Parks and Recreation, Olivette Sustainability Advocates, and Open Space STL, volunteers help remove litter and debris to improve water quality and support wildlife. This hands-on effort promotes environmental stewardship while enhancing local parks and green spaces. Join us in making a lasting impact on the health of the River des Peres and the greater St. Louis region. Youth under the age of 14 years old must be accompanied by an adult.
